Question

Pllzlzz answer

The length of the base of an isosceles triangle is x. The length of a leg is 2x - 4 . The perimeter of the triangle is 24 . Find x rounded to the whole number ?
12 - 24 - 10 - 6 ? which one

Answer 1

x ≈ 6

Explanation:

The legs of an isosceles triangle are congruent , both 2x - 4 , then

x + 2x - 4 + 2x - 4 = 24 , that is

5x - 8 = 24 ( add 8 to both sides )

5x = 32 ( divide both sides by 5 )

x = 6.4 ≈ 6 ( to the nearest whole number )
